If pests are spreading on the Indian cane, you should act quickly. These three are the most well-known canna pests.
The Indian flower cane, also known as Canna or Canna indica, not only exudes southern flair with its appearance, it is also a real feast for the eyes in the garden and on the terrace or balcony. Unfortunately, as with every plant, there are one or two pests that like to tamper with the plant. In principle, there are not many pests that bother Canna. On the other hand, they can sometimes cause greater damage.
These pests can occur
➤ Slugs:
Nudibranchs are among the most important pests of Indian cane. A clear sign of an infestation are punctured leaves and slime tracks.
Combat:
You can fight slugs, e.g. by collecting them at regular intervals or by laying out slug pellets.
➤ Whitefly:
The Indian cane sometimes also suffers from whitefly. The pests usually sit under the leaves of the plant. If you touch the Indian flower cane, they usually fly up in quite a large number. In addition, yellow spots on leaves and dried up and subsequently falling leaves can indicate a whitefly infestation.
Combat:
If you want to fight the whitefly, you can use yellow boards or stickers. These are used near the plant. The whitefly sticks to it and eventually dies. However, it is also possible to rely on natural predators such as arch or parasitic wasps.
➤ Aphids / Voles:
The Indian canna is not spared by aphids or voles, but these usually cause hardly any significant damage to the plant.
Combat:
Since they don't do much damage, there is usually little need to take countermeasures. If you still want to do something against the aphids, you can, for example, rely on natural predators such as the ladybug.Voles, on the other hand, can be caught with traps and released elsewhere.
